The emf of a Daniel cell at 298K is \[{{E}_{1}}\] \[Zn|\underset{(0.01\,\,M)}{\mathop{ZnS{{O}_{4}}}}\,||\underset{(1.0\,\,M)}{\mathop{CuS{{O}_{4}}}}\,|Cu\] when the concentration of \[ZnS{{O}_{4}}\] is 1.0 M and that of \[CuS{{O}_{4}}\] is 0.01 M, the emf changed to \[{{E}_{2}}\]. What is the relationship between \[{{E}_{1}}\] and \[{{E}_{2}}\] [CBSE PMT 2003] |
| A. | \[{{E}_{2}}=0\ne {{E}_{1}}\] |
| B. | \[{{E}_{1}}>{{E}_{2}}\] |
| C. | \[{{E}_{1}}<{{E}_{2}}\] |
| D. | \[{{E}_{1}}={{E}_{2}}\] |
| Answer» C. \[{{E}_{1}}<{{E}_{2}}\] | |
